Evaluate​ f(x) at the given values of x.
​f(x)equals7 xxequalsminus3​, 5

The given function is \( f(x) = 7x \), and you're asked to evaluate it for \( x = -3 \) and \( x = 5 \).

Let's calculate the values:

1. For \( x = -3 \):
   \[
   f(-3) = 7(-3) = -21
   \]

2. For \( x = 5 \):
   \[
   f(5) = 7(5) = 35
   \]

Thus, the evaluations are:
- \( f(-3) = -21 \)
- \( f(5) = 35 \)

Here are 5 related questions to expand on this topic:
1. What happens to \( f(x) \) if \( x = 0 \)?
2. How would the function change if \( f(x) = 7x + 2 \)?
3. What is the slope of the function \( f(x) = 7x \)?
4. How would you solve for \( x \) if \( f(x) = 49 \)?
5. How do you determine if a function is linear or nonlinear?

**Tip:** When evaluating functions, substitute the given value of \( x \) directly into the function and simplify step by step.
